Microchip Technology's 25AA320A-I-ST is a 32 Kbit serial EEPROM utilizing CMOS technology. This memory component, organized as 4K x 8, supports SPI serial bus communication with a maximum clock frequency of 10 MHz. It features a broad operating voltage range from 1.8V to 5.5V, enabling operation at 1.8V minimum at 3 MHz. The 25AA320 series component offers robust data retention of 200 years and an endurance rating of 1,000,000 write cycles. Its 8-pin TSSOP package is designed for surface mounting with a 0.65 mm terminal pitch. Applications include industrial automation, automotive systems, and consumer electronics. The device supports both hardware and software write protection, with a programming voltage of 2.5V and a typical standby current of 1 µA.
